The Triassic succession in the central Midlands in its regional setting

Abstract

Recent deep boreholes in a small area near Bromsgrove and Droitwich in the Worcester Basin of Triassic times have provided a virtually complete Triassic succession, 3350 ft thick, which displays cyclic desert-sedimentation throughout, although the cyclothems differ in the three main rock groups. The sequences proved in many other borings in Worcestershire, Birmingham and Warwickshire, and a few in other parts of the central Midlands, are taken into account, subjected to cyclic analysis, and the results collated_•
